Ant(h)on Ludwig JOHANNSEN of Schleswig-Hostein

I am searching for information on the family of Ant(h)on Ludwig JOHANNSEN.He was born in 1781 in Schleswig-Holstein. In 1818, he married Dorothea Friederica LIND(N)ER, born in 1790 in Bisdorf. They had at least two children:Johann Christian August born in 1822 in Orth auf Fehmarn and Antonia.Any information about this family would be appreciated.
